Integrating Jenkins with version control systems (e.g. Git)

Integrating Jenkins with a version control system (VCS) allows Jenkins to automatically build and test your code whenever changes are committed to the VCS. Some common VCS systems that Jenkins can integrate with are Git, Subversion, and Mercurial. Here's how you can integrate Jenkins with a Git repository:

1. Install Git plugin: To integrate Jenkins with Git, you need to have the Git plugin installed. You can install the plugin from the "Manage Plugins" section in the Jenkins admin console.

2. Create a Jenkins job: In Jenkins, create a new job for your project. In the "Source Code Management" section, select "Git" as the VCS and enter the repository URL.

3. Configure build triggers: In the "Build Triggers" section, configure the triggers that you want to use to start builds. For example, you can configure Jenkins to build whenever changes are pushed to the Git repository.

4. Add build steps: In the "Build" section, add the steps that you want Jenkins to perform when building your project. For example, you can run tests, compile your code, or generate a report.

5. Save and run the job: Save your job and run it manually to confirm that everything is set up correctly.

That's it! Jenkins is now integrated with your Git repository, and it will automatically build and test your code whenever changes are committed to the repository.

Here's a similar example of integrating Jenkins with a Subversion repository:

1. Install Subversion plugin: To integrate Jenkins with Subversion, you need to have the Subversion plugin installed. You can install the plugin from the "Manage Plugins" section in the Jenkins admin console.

2. Create a Jenkins job: In Jenkins, create a new job for your project. In the "Source Code Management" section, select "Subversion" as the VCS and enter the repository URL.

3. Configure build triggers: In the "Build Triggers" section, configure the triggers that you want to use to start builds. For example, you can configure Jenkins to build whenever changes are committed to the Subversion repository.

4. Add build steps: In the "Build" section, add the steps that you want Jenkins to perform when building your project. For example, you can run tests, compile your code, or generate a report.

5. Save and run the job: Save your job and run it manually to confirm that everything is set up correctly.

These are just a few examples of integrating Jenkins with version control systems. You can integrate Jenkins with any VCS that you use, and the steps are similar to what is described above.
